starting to add tests for WFS 1.1.0

make sure we don't override the wfs:FeatureCollection reader with the one from GML
ability to read boundedBy from FeatureCollection
need the ability to set axisOrientation

We need to be able to set axisOrientation on the underlying GML parser of the Filter subparser of ol.parser.WFS*, also only options and no properties on the instance anymore
write out GetFeature in WFS 1.1
port over another WFS 1.1 testcase
ability to parse a FeatureCollection

The trick here was to delete featureNS so autoConfig would kick in
more tests and typedefs.

Once feature editing is more stable, this format can be extended with Update, Delete and Insert
same solution for axisOrientation as for WFS 1.1.0
move the typedefs out of objectliterals
rename this.gml_ to this.gmlParser_
